Use
<code class="docutils literal notranslate"><span class="pre">$&lt;CONFIG&gt;</span></code> instead.</p>
</div>
<p>Build-time reference to per-configuration output subdirectory.</p>
<p>For native build systems supporting multiple configurations in the
build tree (such as <a class="reference internal" href="../manual/cmake-generators.7.html#visual-studio-generators"><span class="std std-ref">Visual Studio Generators</span></a> and <span class="target" id="index-0-generator:Xcode"></span><a class="reference internal" href="../generator/Xcode.html#generator:Xcode" title="Xcode"><code class="xref cmake cmake-generator docutils literal notranslate"><span class="pre">Xcode</span></code></a>),
the value is a reference to a build-time variable specifying the name
of the per-configuration output subdirectory.  On <a class="reference internal" href="../manual/cmake-generators.7.html#makefile-generators"><span class="std std-ref">Makefile Generators</span></a>
this evaluates to <cite>.</cite> because there is only one configuration in a build tree.
Example values:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>$(ConfigurationName) = Visual Studio 9
$(Configuration)     = Visual Studio 11 and above
$(CONFIGURATION)     = Xcode
.                    = Make-based tools
.                    = Ninja
${CONFIGURATION}     = Ninja Multi-Config
</pre></div>
</div>
<p>Since these values are evaluated by the native build system, this
variable is suitable only for use in command lines that will be
evaluated at build time.  Example of intended usage:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>add_executable(mytool mytool.c)
add_custom_command(
  OUTPUT out.txt
  COMMAND ${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool
          ${CMAKE_CURRENT_SOURCE_DIR}/in.txt out.txt
  DEPENDS mytool in.txt
  )
add_custom_target(drive ALL DEPENDS out.txt)
</pre></div>
</div>
<p>Note that <code class="docutils literal notranslate"><span class="pre">CMAKE_CFG_INTDIR</span></code> is no longer necessary for this purpose but
has been left for compatibility with existing projects.  Instead
<span class="target" id="index-0-command:add_custom_command"></span><a class="reference internal" href="../command/add_custom_command.html#command:add_custom_command" title="add_custom_command"><code class="xref cmake cmake-command docutils literal notranslate"><span class="pre">add_custom_command()</span></code></a> recognizes executable target names in its
<code class="docutils literal notranslate"><span class="pre">COMMAND</span></code> option, so
<code class="docutils literal notranslate"><span class="pre">${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool</span></code> can be replaced
by just <code class="docutils literal notranslate"><span class="pre">mytool</span></code>.</p>
<p>This variable is read-only.  Setting it is undefined behavior.  In
multi-configuration build systems the value of this variable is passed
as the value of preprocessor symbol <code class="docutils literal notranslate"><span class="pre">CMAKE_INTDIR</span></code> to the compilation
of all source files.</p>
